~enzoyl derivatives
The present invention relates to novel benzoyl derivatives having
S herbicidal action, processes for preparing the benzoyl deriva-
tives, compositions which contain the latter and the use of these
derivatives or compositions contAining the latter for controlling
weeds .
10 ~erbicidally activ~ 2-aroylcycloheY~ne~iones are disclo~ed in the
literature, for example in EP 283261, EP 90262, EP 135191,
EP 18611~, EP 186119, EP 186120, EP 319075, WO 9005712,
WO 9404524, NO 9408988, JO3052862 and JO 3120202.
15 The herbicidal properties of the known compounds and the toler-
ability for crop plants, however, are only satisfactory to a
limited extent.
It is an ob~ect of the present invention to find novel 2-aroyl-
20 cyclohey~nediones having improved properties.

In the above scheme 1, T in said formulae has the meaning halogen
25 or OH and L, M, X, Y and n have the ~~.nings given above.
The first step of the reaction sequence, the acylation, is car-
ried out in a generally known manner, eg. by adding an acid chlo-
ride of the formula III (T=Cl) or a carboxylic acids [sic] III
30 (T=OH) activated, for example, with DCC (dicyclocarbodiimides
[sic]) or similar agents known from the literature, eg. triphe-
nylphosphine/DEAD = diethyl azodicarboxylate, 2-pyridine tsic]
disulfide~triphenylphosphine to the solution or suspension of a
cyclohexanedione II, if appropriate in the presence of an auxil-
35 iary base. The reactants and the auxiliary base are in this casee~pe-~;iently employed in equimolar amounts. A small excess, eg.
from 1.2 to 1.5 molar equivalents, based on II, of the auxiliary
base can be advantageous under certain circumstances.
~-.0 Suitable auxiliary bases are tertiary alkylamines, pyridine or
alkali metal carbonates. The solvents used can be, eg. methylene
chloride, dioxane, diethyl ether, toluene, acetonitrile or ethyl
acetate.
~5 During the addition of the acid chloride, the reaction mixture i~
preferably cooled to from O to 10~C, then it is stirred at from 20
to 100 C, in particular 25 to 50 C, until the reaction is
CA 02227934 1998-02-23
0050/46142
complete. Working up is carried out in the customary manner, eg.
the reaction mixture is poured into water and the useful product
is extracted, eg. with methylene chloride. After drying the or-
ganic phase and removing the solvent, the crude enol ester can be
5 employed without further purification for the rearrangement.
Preparation examples for benzoyl enol esters of cyclohex-
ane-1,3-diones are found, for example, llacuna] EP-A 186 118 or
US 4,780,127.
10 The rearrangement of the enol esters to the compounds of the for-
mula Ia-Ie is expediently carried out at from 20 to 40~C in a sol-
vent and in the presence of an auxiliary base and also with the
aid of a cyano compound as a catalyst.
15 The solvents used can be, eg. acetonitrile, methylene chloride,
1,2-dichloroethane, ethyl acetate or toluene. A preferred solvent
is acetonitrile. Suitable auxiliary bases are tertiary alkyla-
mines, pyridine or alkali metal carbonates, which are preferably
employed in equimolar amounts or up to a four-fold excess, based
20 on the benzoyl enol ester. A preferred auxiliary base i8 tri-
ethylamine in twice the amount.
Suitable catalysts are potassium cyanide, acetone cyanohydrin and
trimethylsilyl cyanide, preferably in an amount of from 1 to
25 50 mol percent, based on the enol ester. Preferably, acetone cya-
nohydrin is added, eg. in the amounts from 5 to 15, in particular
10 mol percent. Examples of the cyanide-catalyzed rearrangement
of enol esters are found, for example, in EP-A 186118 or
US 4,780,127.
Working up is carried out in a manner known per se, eg. the reac-
tion mixture iB acidified with dilute mineral acids such as 5 9c
strength hydrochloric acid or sulfuric acid and extracted with an
organic solvent such as methylene chloride or ethyl acetate. For
35 purification, the extract is extracted with cold 5 to 10 %
strength alkali metal carbonate solution, the final product pass-
ing into the aqueous phase. By acidifying the aqueous solution,
the product of the formula Ia-Ie is precipitated or extracted
again with methylene chloride or ethyl acetate, dried and then
40 freed from the solvent.
The 1,3-diketones of the formula II used as a starting material
are known and can be prepared by processes known per se, such as
are described, for example, in EP-A 71707, EP-A 142741, EP-A
45 243313, uS 4,249,937 and wo 92~13821. Cyclohexanedione and
dimedone are commercially available compounds.

Benzoic acids of the formula III can be prepared as follows:
Benzoyl halides, for example benzoyl chlorides of the formula III
(T = Cl), are prepared in a known manner by reactin~g the benzoic
5 acids of the formula III ~T = OH) with thionyl chloride.
The benzoic acids of the formula III (T = OH) can be prepared in
a known manner by acidic or basic hydrolysis of the corresponding
esters of the formula III (T = C1-C4-alkoxy).
:LO The inteL ~ tes of the formula III are known in some cases or
can be prepared by processes known from the literature.

After this, for example, arylthio compounds IY as shown in scheme
2 can be reacted with substituted haloalkenyl [sic] as described
in J. Med. Chem. 1984, 27, 1516, substituted alkynylcarboxylic
acids as described in J. Org. Chem. 1980, 45, 4611 or J. Am.
4LO Chem. Soc. 1983, 105, 883, substituted haloalkylcarboxylic acids
as desribed in Chem. Ber. 1925, 58, 1612 in the presence of a
base such as alkali metal hydroxide, alkali metal hydride or
alkali metal carbonate. The resulting compounds V are cyclized to
VI under Friedel-Crafts conditions with addition of a Lewis acid
4L5 or a protic acid. Preferred Lewis acids are AlC13 or SnCl4 and
preferred protic acids are polyphoshoric [ 8iC] acid and sulfuric
acid as described in Can. J. Chem. 1981, 59, 199; Chem. Ber.

Thiochromenone acids can furthermore be prepared by, for example,
5 elimination of hydrogen halide from 3-halothiochromanone acids
or, for example, by reaction of the subfitituted thiophenol acids
with substituted a-alkylacetic ester~ in the presence of
phosphorus pentoxi~e as described in Ann. Chem. 1964, 680, 40.
~0 The arylthio compounds IV can be obtained, for example, by Sand-
meyer reaction from corresponding anilines, which for their part
are synthesized by reduction of suitable nitro compounds a~ de-
scribed in Organicum l9th Edition 1992, 552 ff.
15 In the case where, for example, X i9 equal to (-CRl2Rl3-) or
(-CRl2Rl3CR2lR22-), Y is equal to C=O and T i~ equal to
Cl-C4-alkoxy, the thiochromonone ester or dihydrobenzothiophene
ester as described in scheme 2 can be prepared by alkylation of
the arylthio compound IV with halopropionic acid or haloacetic
;~0 acid in solvent or water in the presence of one of the
abovementioned bases and cyclized to VI.
The reactantq and the base are in thi~ ca~e eYre~iently employed
in equimolar amounts. The reaction mixture is preferably stirred
;25 at 20-100 C, in particular at 20-40 C. Working-up is carried out,
for example, in ~uch a way that the reaction mixture is poured
onto water, the aqueous phase is rendered acidic using mineral
acids such a~ hydrochloric acid or sulfuric acid and the u~eful
product is filtered off with suction or extracted by extraction
.lO l~icl with methylene chloride or ethyl acetate, and the extract
is dried and freed from the solvent. The ester can be reacted
without further purification.
By stirring V in, for example, polyphosphoric acid at 40-140 C, in
35 particular at 70-100~C, or by activating the carboxylic acid by
conversion into the acid chloride and stirring with 2-6, in par-
ticular 3.5 to 4.5, mol equivalents of a Lewis acid such as AlC13
or SnCl4 in a solvent or by stirring with or in sulfuric acid, an
intermediate of the formula III is obtained by working up in a
~IO manner known per se, ie. adding ice water and filtering off the
useful product with suction or extracting the aqueous phase with
ethyl acetate or methylene chloride, drying and removing the
solvent.
~15 In the case where, for example, X is equal to an ethylene group
~-CR12=CRl3-), Y is equal to C=O and T is equal to C1-C4-alkoxy,
the thiochromenone ester can be converted by, for example,
CA 02227934 1998-02-23
0050/46142
reaction of an arylthio compound ~ith an acetylenecarboxylic acid
derivative in water or solvent at 0-140 C. Working up is carried
out in a manner known per se by adding water and dilute mineral
acid, eg. hydrochloric acid. The useful product is either fil-
5 tered off with suction or obt~i n~ by extraction with methylenechloride or ethyl acetate, then drying and removing the solvent.
The intermediates of the formula III can be further functional-
ized by reactions known from the literature, ~uch as reduction as
l0 described in Jerry March, Advanced Organic Chemistry, Fourth Ed.,
eg. p.910ff, oximation as described in Jerry March, Advanced
organic Chemi~try, Fourth Ed., eg. p. 934, 935, 1039, 1226,
405ff, conversion into imines and amines as described in Jerry
March, Advanced Organic Chemistry, Fourth Ed., ketalization,
15 alkylation, halogenation, elimination and oxidation as described
in Jerry March, Advanced Organic Chemi~try, Fourth Ed.
The acids of the 3-alkoxy-1,2-benzisothiazole-1,1-dioxides or
3-alkoxy-1,2-benzisothiazoles can be obtained starting from cor-
20 responding ~AcchArin derivatives or 1,2-benzisoth;A~oles by, for
example, reaction with PCl5, POC13 or chlorine and alcohol, if ap-
propriate in the presence of an auxiliary base ~uch as triethyl-
amine, which is described, for example, in US 4,571,429, Arch.
Pharm. 1984, 317, 807, US 4461901, VS 450916, J. Med. Chem. 1986,

known from the literature a~ described in Ann. Chem. 427, 231,

The derivative~ of the benzo-1,4-oxathiin acids are known in some
cases, eg. from J. Org. Chem. 1968, 33, 456 or can be
synthesized, for example, by reaction [sic] from the
corre~ponding phenol derivatives as described in Chem. Comm.,
35 1975, 451, J. org. Chem. 1974, 39, 1811, J. Am. Chem. Soc. 1954,
76, 1068 or by combination of, for example, substitution
reaction~ of halogen-sub~tituted thiophenol derivativeR and
secondary reactions such as oxidation, reduction or addition a~
described in J. Het. Chem. 1983, 20, 867.

Y,L,M,X, have the meanings de~cribed above
with carbon monoxide and water at elevated pressure in the pres-
ence of a palladium, nickel, cobalt or rhodium transition metal
15 cataly~t and a base.
The catalysts nickel, cobalt, rhodium and in particular palladium
can be present in metallic form or in the form of customary
salts, such as in the form of halogen compounds, eg. PdC12,
20 RhCl3-H20, acetates, eg. Pd~OAc)2, cyanides etc., in the known
valency states. Metal complexes with tertiary phosphines, metal
alkylcarbonyls, metal carbonyls, eg. CO2~CO)8, Ni~CO) 4, metal
carbonyl complexes with tertiary phosphines, eg. (PPh3)2Ni(CO) 2~
or transition metal salts complexed with tertiary phosphines can
25 further be present. The last-mentioned embodiment iB preferred,
in particular, in the case of palladium as a catalyst. The nature
of the phosphine ligands here is widely variable. For example,
they can be repre~ented by the following formulae:
~ R24 R24~ ~ R26
P ~ R25 or R2s ~ P (CH2)~ - P ~
where n is the numbers 1, 2, 3 or 4 and the radicals R24 to R27
35 are low molecular weight alkyl, eg. Cl-C6-alkyl, aryl,
Cl-C4-alkylaryl, eg. benzyl, phenethyl or aryloxy. Aryl is, for
example, naphthyl, anthryl and preferably unsubstituted or
~ubstituted phenyl, where with respect to the sub~tituents
attention only has to be paid to their inertness to the
40 carboxylation reaction, otherwise they can be widely varied and
include all inert C-organic radicals such as C1-C6-alkyl r~icAls~
eg. methyl, carboxyl radicals such as COOH, COOM (M is, for
example, an alkali metal, alkaline earth metal or ammonium salt
[sicl), or C-organic radicals bonded via oxygen, such as
45 C1-C6-alkoxy radicals.
CA 02227934 1998-02-23
0050/46142
The phosphine complexes can be prepared in a manner known per se,
eg. as described in the documents mentioned at the outset. For
example, the starting materials used are customary commercially
available metal salts such as PdCl2 or Pd(OCOCH3)2 and the
5 phosphine for example P(c6Hs)3~ P(n-C4Hs)3, PCH3(C6Hs) 2r
1,2-bis(diphenylphosphino)ethane is added.
The amount of phosphine, based on the transition metal, is cus-
tomarily from O to 20, in particular 0.1 to 10, mol equivalents,
10 particularly preferably 1 to 5 mol equivalents.
The amount of transition metal is not critical. Of course, for
co~t reason~, rather a small amount, eg. from 0.1 to 10 mol%, in
particular from 1 to 5 mol%, based on the starting substance II
15 or III, is used.
For the preparation of the benzoic acids III (T = OH), the reac-
tion is carried out with carbon monoxide and at least equimolar
amounts of water, based on the starting ~ubstanceQ VI. The reac-
20 tion component water can simultaneously be used also as a sol-
vent, ie. the maximum amount is not critical.
However, depenAing on the starting substances and the catalyst~
used, it can al~o be advantageous instead of the reaction compo-
25 nent to use as the solvent another inert solvent or the base usedfor the carboxylation.
Suitable inert solvents are solvents customary for carboxylation
reaction~, such a~ hydrocarbons, eg. toluene, xylene, hex~ne~
30 pentane, cyclohexane, ethers, eg. methyl tert-butyl ether, tetra-
hydrofuran, dioxane, dimethoxyethane, substituted amides such as
dimethylformamide, persubstituted ureas ~uch as tetra-Cl-C4-alkyl-
ureas, or nitriles such as benzonitrile or acetonitrile.
35 In a preferred embodiment of the process, one of the reaction
components, in particular the base, is used in an excess 80 that
no additional solvent is necessary.
Bases suitable for the process are all inert bases which are able
40 to bind the hydrogen iodide or hydrogen bromide liberated in the
reaction. Examples which may be mentioned here are tertiary
amines such as tert-alkylamines, eg. trialkylamines such as tri-
ethylamine, cyclic amines such a~ N-methylpiperidine or N,N'-di-
methylpiperazine, pyridine, alkali metal carbonates or hydrogen
45 carbonates, or tetraalkyl-substituted urea derivatives such as
tetra-Cl-C4-alkylurea, eg. tetramethylurea.
CA 02227934 1998-02-23
0050/46142
The amount of base is not critical, customarily from 1 to 10, in
particular from 1 to 5, mol are u~ed. When the base is simulta-
neously used as a solvent, the amount is generally proportioned
such that the reaction components are dis~olved, unnecessarily
5 high excesses being avoided for practicability reasons, in order
to save costs, to be able to employ small reaction vessels and to
guarantee maximum contact of the reaction components.
During the reaction, the carbon monoxide pressure is adjusted
10 ~uch that an excess of C0, based on VI, is always present. Pre-
ferably, the carbon monoxide pressure at room temperature is from
1 to 250 bar, in particular from 5 to 150 bar of CO [sic].
The carbonylation is generally carried out continuously or batch-
15 wise at from 20 to 250 C, in particular 30 to 150 C. In the ca~e
of batchwise operation, carbon monoxide iB expediently injected
into the reaction mixture continuously to maintain a constant
pressure.
20 The arylhalogen compounds VII used as starting compounds are
known or can easily be prepared by suitable combination of known
synthe~es and by reaction sequences described above.
With respect to the inte~ed use of the benzoyl derivatives of

The compounds I and their agriculturally utilizable salts are
suitable as herbicides, both in the form of isomer mixtures and
in pure isomer form. The isomer-cont~ining herbicidal composi-
5 tions provide highly effective control of plant growth on un-
cultivated areas, in particular at high application rates. They
act against broad-leaved weeds and grass weeds in crops such as
wheat, rice, maize, soybeans and cotton without significantly
harming the crop plants. This effect occurs especially at low ap-
10 plication rates.
In consideration of the versatility of the application methods,the compounds I or compositions contAi~ing them can additionally
be employed in a further number of crop plants for the
15 elimination of undesired plants. Suitable crops, for example, are
the following:
Allium cepa, AnAnA~ comosus, Arachis hypogaea, Asparagus
officinalis, Beta vulgaris spec. altissima, Beta vulgaris spec.
20 rapa, Brassica napus var. napus, Bra-qsica napus var.
~pobra~sica, Brassica rapa var. silvestris, Camellia sinensis,
Carthamus tinctorius, Carya illinoinensis, Citrus limon, Citrus
sinensis, Coffea arabica (Coffea canephora, Coffea liberica),
Cucumis sativus, Cynodon dactylon, Daucus carota, Elaeis
25 guineensis, Fragaria ve~ca, Glycine max, Gossypium hirsutum
(Go~sypium arboreum, Goqsypium herbaceum, Gossypium vitifolium),
Helianthus annuus, Hevea brasiliensis, Hordeum vulgare, Humulus
lUpUlU9, Ipomoea batatas, Juglans regia, Lens culinaris, Linum
usitatissimum, Lycopersicon lycopersicum, Malus spec., Manihot
30 esculenta, Hedicago sativa, Musa spec., Nicotiana tabacum
(N. rustica), Olea europaea, Oryza sativa, Phaseolus lunatus,

35 tuberosum, Sorghum bicolor (s. vulgare), Theobroma cacao,
Trifolium pratense, Triticum aestivum, Triticum durum, Vicia
faba, Vitis vinifera, Zea mays.
Moreover, the compounds I can also be u~ed in crops which are
40 tolerant to the action of herbicides as a result of breeding,
including genetic engineering~methods.
The compDunds I and the herbicidal compositions contA;n;ng them
can be applied by spraying, atomizing, dusting, scattering or
45 watering, for example in the form of directly sprayable aqueous
solution~, powders, suspensions, even high-percentage aqueous,
oily or ~Dther suspensions, or dispersions, emulsions, oil disper-

sions, pastes, dusting compositions, scattering compositions or
granules. The application forms depend on the intended uses; in
each case they should if possible ensure the finest dispersion of
the active compounds according to the invention.
Suitable inert additives are mineral oil fractions of medium to
high bo;Lling point, such as kerosene or diesel oil, further coal
tar oils and oils of vegetable or animal origin, aliphatic,
cyclic and aromatic hydrocarbons, eg. paraffin, tetrahydronaph-
10 thalene, alkylated naphthalenes or their derivatives, alkylatedhenzene3 or their derivatives, methanol, ethanol, propanol, buta-
nol, cyclohexanol, cyclohexanone or strongly polar solvents, such
as N-methylpyrrolidone or water.
15 Aqueous application forms can be prepared from emulsion concen-
trates, dispersions, pastes, wettable powders or water-dispers-
ible granules by addition of water. To prepare emulsions, paste~
or oil dispersions, the substrates 1 8iCl can be homogenized in
water as such or dissolved in an oil or solvent, by means of wet-
20 ting agentR, adhesives, dispersants or emulsifiers. However, con-
centrates consisting of active sub~tance, wetting agent, adhes-
ive, di,3persant or emul~ifier and possibly solvent or oil can
also be prepared which are suitable for dilution with water.
25 Suitable surface-active substances (adjuvants) are the Alk~
metal, alkaline earth metal or ammonium salts of aromatic sul-
fonic acids, eg. lignosulfonic, phenolsulfonic, naphthalenesul-
fonic and dibutylnaphthalenesulfonic acid, and also of fatty
acids, alkyl and alkylarylsulfonates, alkyl, lauryl ether and
30 fatty aLcohol sulfates, as well as salts of sulfated hexa-,
hepta- and oct~ec~nols, and also of fatty alcohol glycol ether,
condensation products of sulfonated naphthalene and its deriva-
tives with formaldehyde, condensation products of naphthalene or
of the naphthalenesulfonic acids with phenol and formaldehyde,
35 polyoxyethylene octylphenol [sic] ethers, ethoxylated isooctyl-,
octyl- or nonylphenol, alkylphenyl or tributylphenyl polyglycol
ethers, alkyl-aryl polyether alcoholR, isotridecyl alcohol, fatty
alcohol--ethylene oxide condensates, ethoxylated castor oil, poly-
oxyethyLene alkyl ethers or polyoxypropylene alkyl ethers, lauryl
40 alcohol polyglycol ether acetate, sorbitol esters, lignin-sulfite
waste l:iquors or methylcellulose.
Powder, scattering and dusting compositions can be prepared by
i~ing or joint grinding of the active subst~nces with a solid
45 carrier.

Granules, eg. coated, impregnated and homogeneous granules, can
be prepared by binding the active compounds to ~olid carriers.
Solid carriers are mineral earths such as silicic acids, silica
gels, silicates, talc, kaolin, limestone, lime, chalk, bole,
5 loess, ,clay, dolomite, diatomaceous earth, calcium sulfate and
magnesium sulfate, magnesium oxide, ground synthetic materials,
fertilizers, such as ammonium sulfate, ammonium phosphate, ammon-
ium nitrate, ureas and vegetable products, such as grain flour,
tree bark, wood and nutshell meal, cellulose powder or other
10 solid carriers.
The concentrations of the active compounds I in the ready-to-use
preparations can be varied within wide ranges. The formulations
in general contain from 0.001 to 98% by weight, preferably from
15 0.01 to 95% by weight, of at least one active compound. The
active compounds are employed here in a purity of from 90 to
100%, preferably 95 to 100% (according to NMR spectrum).
The compounds I according to the invention can be formulated, for
20 example, as follows

product of from 8 to 10 mol of ethylene oxide to 1 mol of
oleic acid N-monoethanolamide, 5 parts by weight of cal-
cium dodecylbenzenesulfonate and 5 parts by weight of the
addition product of 40 mol of ethylene oxide to 1 mol of

oil. By pouring the solution into and finely dispersing
it in 100,000 parts by weight of water, an aqueous dis-
persion is obtained which contains 0.02% by weight of the
active compound.

oil fraction of boiling point from 210 to 280~C and 10
parts by weight of the addition product of 40 mol of
ethylene oxide to 1 mol of ca~tor oil. By pouring the
solution into and finely dispersing it in 100,000 parts
by weight of water, an aqueous dispersion is obtained
which contains 0.02% by weight of the active compound.

water, a spray mixture is contAineA [sic] which contains
0.1% by weight of the active compound.
V. 3 parts by weight of the active compound No. 13.5 are
mixed with 97 parts by weight of finely divided kaolin.

dissolved in a mixture which consists of 70 parts by
weight of cycloh~none, 20 parts by weight of ethoxy-
lated isooctylphenol and 10 parts by weight of ethoxy-
lated castor oil. A stable emulsion concentrate is ob-
tA i ne~ .

weight of cyclohe~Ansne and 20 parts by weight of Wettol~
EM 31 (= nonionic emulsifier based on ethoxylated castor
oil). A stable emulsion concentrate is obtA j n~ .
The app:Lication of the active compounds I or of the herbicidal
45 composi1ions can be carried out pre ~ -rgence or post-emergence.
If the active compounds are less tolerable for certain crop
plants, application techniques can be used in which the herbici-

241
dal compositions are sprayed with the aid of the 6pray equipment
such that the leaves of the sensitive crop plants are not
affected if possible, while the active compounds reach the leaves
of undesired plants growing under them or the uncovered soil
5 surface (post-directed, lay-by).
Depending on the aim of control, time of year, target plants and
stage of growth, the application rates of active compound are
from 0.001 to 3.0, preferably from 0.01 to 1.0, kg/ha of active
10 substance (a.s.).
To widen the spectrum of action and to achieve synergistic ef-
fects, the benzoyl derivatives I can be mixed and applied
together with numerous representatives of other herbicidal or
15 growth-regulating active compound groups. For example, suitable
mixture components are 1,2,4-thiA~iazoles, 1,3,4-thiA~iAzoles,
amides, aminophosphoric acid and its derivatives, aminotriazoles,
anilides, aryloxy-/heteroaryloxyAlkAnoic acids and their deriva-
tives, benzoic acid and its derivatives, benzothiA~iAzinones,
20 2-(heteroaryl/aroyl)-1,3-cyclohexadiones, heteroaryl aryl ke-
tones, benzylisoxazoli~ino~s, meta-CF3-phenyl derivatives, carba-
mates, ,quinolinecarboxylic acid and its derivatives, chloroacet-
anilides, cycloheYAne-1,3-dione derivatives, diazines, dichloro-
propionic acid and its derivatives, dihydrobenzofuran~, dihy-
25 drofuran-3-ones, dinitroanilines, dinitrophenols, diphenyl
ether~, dipyridyls, halocarboxylic acids and their derivatives,
ureas, 3-phenyluracils, imidazoles, imidazolinones, N-phe-
nyl-3,4,5,6-tetrahydrophthalimides ~ OYA~ i A zoles, oxiranes,
phenols, aryloxy- and heteroaryloxyphenoxypropionic acid esters,
30 phenylacetic acid and its derivatives, 2-phenylpropionic acid and
its derivatives, pyrazoles, phenylpyrazoles, pyridazines, pyri-
dinecarboxylic acid and its derivatives, pyrimidyl ethers,
sulfonamides, sulfonylureas, triazines, triazinones, triazoli-
nones, ltirazolecarboxamides and uracils.
Additionally, it may be useful to apply the c- ,-unds I on their
own or in combination with other herbicides additionally mixed
with further crop protection agents, for example with agents for
control:Ling pests or phytopathogenic fungi or bacteria. Further
40 of interest is the miscibility with mineral salt solutions, which
are emp:Loyed for the elimination of nutritional and trace element
deficiencies. Nonphytotoxic oils and oil concentrates can also be
added.

It was Ipossible to show the herbicidal action of the benzoyl de-
rivatives of the formula I by greenhouse tests:
The cultivation contA;ners used were plastic flowerpots contain-
ing loamy sand with about 3.0% humus as a substrate. The seeds of
the test plants were sown separately according to species.
lO In the case of pre-emergence treatment, the active compounds sus-
pended or emulsified in water were applied directly after sowing
by means of finely dispersing nozzles. The containers were light-
ly wate:red to promote germination and growth and then covered
with transparent plastic hoods until the plants had taken root.
15 Thi~ corering causes uniform germination of the test plants if
this has not been adversely affected by the active compounds.
For the purposes of post-emergence application, the test plants,
depen~ g on growth form, were first raised to a height growth of
20 from 3 ltO 15 cm and only then treated with the active compounds
suspe~e~ or emulsified in water. For this purpose, the test
plants were either sown directly and grown in the same contA~rs
or they were first raised separately as seedlings and trans-
planted into the test contAin~rs a few days before treatment.
The app:Lication rate for post-emergence treatment was from 0.5 to
0.25 kgJha of a.s.
The plants were kept species-specifically at from 10-25~C or 20-
30 35 C. The test period extended over 2 to 4 weeks. During this
time, the plants were tended and their reaction to the individual
treatments was assessed.
As~;essment was carried out on a scale of from 0 to 100. 100 here
35 means no emergence of the plants or complete destruction of at
least the above-ground parts and 0 means no damage or normal
course of growth.
The plants used in the greenhouse tests were made up of the fol-
